Sealed 10-Circuit Plug Housing for Power Harnesses
The Molex 2143720003 is a 10-position, dual-row plug housing from the Mini-Fit Sigma 214372 series. It is a sealed connector housing — the key feature that sets it apart from the standard Mini-Fit Jr. line — designed for wire-to-board power interconnects in environments where moisture or washdown is a concern.
What the Sealing and Temperature Range Mean for Your Build
The sealed feature means this housing, when mated with the matching receptacle and fitted with the correct seal-capable terminals, is intended for applications where the connection point must resist splash, dust, or direct spray. The locking ramp gives a positive tactile latch that resists vibration-induced disconnect; you'll hear it click when the plug seats into the header.
Mating and Terminal Fit
This plug housing mates with the corresponding Mini-Fit Sigma header of the same circuit count and pitch.
